The XE85 is Sony's competition to the MU7000-9000 but it doesn't come in 49".

How do you use the TV? The MU7000 is a better home theatre TV - people sat directly in front, lights dimmed, high quality content - while the XE80 is probably better for a more casual TV watching. It's got wider viewing angles and will be a bit better in scaling up lower quality content (although both look soft compared to cheaper Full HD models).
